“…Due to the formation of spatters, the powder characteristics in terms of PSD, sphericity, and flowability also undergo variation, as listed in table 3. In terms of PSD, most of the studies have shown that it tends to shift towards coarse particles after reuse [183], due to the agglomeration of spatters [191] and reduction of fine particles [183]. However, different trends, such as a left shift in PSD [192] or no significant change [181], are also found for different alloy systems.…”

“…To date, various titanium and titanium alloys have been extensively investigated via AM technologies, including the workhorse Ti6Al4V, β-type titanium alloy [238,239], and CP-Ti alloy [240]. In consideration of high cost of the titanium and titanium alloys, it is meaningful to understand the variation of powder characteristics and part properties of titanium and titanium alloys with powder reuse [181,183,196,203,204,[241][242][243][244][245].…”

Laser powder bed fusion (L-PBF) has attracted significant attention since its inception, providing unprecedented advantages to fabricate metallic components with complex geometry. The quality and performance of as-printed alloys is an intricate function consisting of numerous factors linking the feedstock powders, manufacturing, and post-treatment. As the starting materials, powders play a critical role in influencing the printing consistency, total fabrication cost, and mechanical properties. In consideration of its importance for L-PBF, the present review aims to review the recent progress on metallic powders for L-PBF focusing on powder characterization, powder fabrication, and powder reuse. The methods of powder characterization and fabrication were presented in the beginning by analyzing the principles and corresponding advantages and limitations. Subsequently, the effect of powder reuse on the powder characteristics and mechanical performance of L-PBF parts is analyzed focusing on steels, nickel-based superalloys, Ti and Ti alloys, and Al alloys. The evolution trend of powders and as-printed parts varies for different alloy systems based on the existing studies, which makes the proposal of a unified reuse protocol infeasible. Finally, perspectives are presented to cater to the increasing applications of AM technologies for future investigations. The present state-of-the-art work can pave the way for the broad industrial applications of L-PBF by enhancing printing consistency and reducing the total cost from the perspective of powders.

“…Extensive research has been conducted in this field; the processing of Ti6Al4V alloy, the most popular titanium-based alloy, has received extensive attention. [25][26][27][28][29][30][31][32][33] In terms of processability, Nguyen et al [34] reviewed the processability of Ti6Al4V by various AM methods, including electron beam melting (EBM), laser powder bed fusion (L-PBF), and directed energy deposition (DED) methods. L-PBF and DED methods exhibit comparable strength to the conventionally produced counterparts, up to 25% higher.…”

The restricted number of materials available for additive manufacturing (AM) technologies is a determining impediment to AM growing into sectors and providing supply chain relief. AM, in particular, is regarded as a trustworthy manufacturing technology to replace the traditional ones for Ti alloy components. Furthermore, the AM processability of Ti alloys and their features, such as microstructure, texture, and mechanical properties, is strongly dependent on the chemical composition of the processed alloy. It is essential to consider the ultimate applications as well. β Ti alloys are gaining popularity in the biomedical industry, while α + β Ti alloys are increasingly utilized for producing components in the automotive and aerospace sectors. Consequently, the topic has garnered considerable interest, and the current text reviews the advances during the last 10 years in this area to facilitate the pathway from the demanded Ti alloy to the best‐fit AM procedure. While systematically reviewing the works published in the literature, the current text attempts to establish a link between the production method, feedstock type, chemical composition, and the ultimate application. This review also features practical applications of Ti components produced by metal AM methods and offers prospective possibilities and industrial applications.
